Sharp MZ-80B boot disk

by avickers＠solutionengineers.com

Does anyone have a working boot disk for a Sharp MZ-80B? I went to use mine for the first time in a few months, and all of the disks are either reporting "Not a Master" or "Read Error". Since I *know* that at least 3 /should/ be bootable[1], there is clearly something awry with either the disks or drives. I'm going to try my spare set of drives tomorrow, but if that doesn't work then I'm stuck :( TIA [1] One of them I made myself, used it, and even labelled it "80B Boot Disk". And that reports "Not a master" now. Grrrr. :( -- Cheers, Ade. Be where it's at, B-Racing! http://b-racing.com

Question about TI calculator

by dmabry＠mich.com

I became the grateful recipient of a TI Programmer today. A buddy at work said "here, you like calculators, right? Better than throwing it away." Well, I said "thanks!" Now, in looking about the internet for some info on the battery styles for these things, I have a couple of questions that I cound't find the answer to. This calculator has a battery pack called BP-8 which has 2 AA ni-cads and a small circuit in it. It connects to the calculator internally with a connector that would also mechanically mate to a 9 volt battery. Now I would not expect a 9 volt battery to work where 2 AA's work, but I'm not sure. In looking at Gene's web site he says the BP-8 is also used on the TI-30 and I see TI-30's on ebay saying that they work with 9 volt batteries. I will replace the two AA's with new ones. That should make the BP-8 good again. I guess the is a roundabout way of asking for some background on the power requirements of this calculator. Unfortunately my buddy had lost the AC adapter (apparently it was an AC-9132, thanks Gene!). So I'll be looking for one of those. 5.7v, 240ma, and that small 2-pin connector. Thanks for any help. -- Dave Mabry dmabry(a)mich.com Dossin Museum Underwater Research Team NACD #2093

ZMAIL goes live

by acme＠ao.net

Hi -- After all the whining I've done on this list concerning virii attacking the Windows-based PC I've been using for email, I'm pleased to announce that it's no longer a problem. This message was composed and mailed using the email system I've been working on -- ZMAIL. The client-side hardware consists of a Zenith Z-100 with 1 20 MB hard drive and 192 KB RAM, plus a 56 K modem. I really don't know what the host machine is, except that it's running Debian Linux. The client-side software consists of an offline email reader/writer -- ZMAILER - -- which has many of the features you'd expect: address book, reply, forward, import file, etc. (no sort capability yet) Additionally, there are utility programs which concatenate the outgoing messages into a single file, break the incoming messages out from a single file, connect to the host, and transfer the data back and forth. On the host side, I wrote programs to grab new incoming mail and pass it to the client, as well as a utility to break out individual outgoing messages from a single file and post them via SMTP. This has been a great learning experience as I had to learn enough about CP/M-86, Linux, SMTP, and the 2661 UART to get this system working. It also (IMHO) is a great use of this classic old Z-100 -- actually two of them, one at home and one at my shop. Anyway, thanks to all of you who very kindly helped me during the course of this project. Especially, thanks to Joe Rigdon, who gave me the Z-100s, and also to Tony Duell, who very patiently helped me with the basics of programming the 2661. Classic computers rule! (even at 2400 baud ;>) Later -- Glen 0/0

Thing to check before powering up DEC VT100

by ian_primus＠yahoo.com

I just acquired a new, unused DEC VT100 terminal. I have not plugged it in yet, because I am a little weary about firing up a piece of 20 year old hardware that has never been turned on before. Something tells me that there are probably some dried up capacitors lurking in there somewhere, just waiting to blow as soon as I flip the switch. Visual inspection really can't tell me anything here, there won't be any burn marks or blown caps in something that has spent it's entire life wrapped in plastic. What areas in particular should I check? Are there any parts that are prone to failure in these terminals? Thanks in advance! Ian Primus ian_primus(a)yahoo.com PS - On a similar note, does anyone know of someplace online that I can find a VT100 keyboard? I have one here, but it's in really terrible shape - very yellow with the name of a school written on it. It works, save for the "Return" key that normally takes two presses to register, but I would like to find something in a bit better shape and with all the keys present and accounted for.

Yes, they can run at a higher clock speed. About the only place you find them are in Atari 520s and 1024s. -- Pete Peter Turnbull Network Manager University of York

Surge protectors or fire hazard

by dwightk.elvey＠amd.com

Hi I've just seen the third surge protector blow up and this time, it almost started a real fire. I've had two of these go up in smoke that were in metal strips. These generally make a lot of smoke but I think the metal spreads the heat enough that the fire danger is small. Now, most of the newer ones are made from plastic. The last one that just burned, started a small fire on the back side of a chest of drawers. Luckily, the chest didn't stay lit. It did charcoalize one of the feet. While these things come with a 15 amp breaker, the MOV's fail and draw something less then what is required to blow the breaker. I wonder if any of the fire prevention groups are looking into these time bombs? Dwight

This is what the metal ones do ( at least the two I've seen go ). It was a plastic one that caused the troubles. When I've looked in the metal ones, I've never seen a separate fuse. I don't know what the plastic one had, it is a melted mess. Dwight > > >

PDP11/44 update, dead wierd fan (35VAC, 75Hz)

by glenslick＠hotmail.com

Well I managed to get a M7095 module ($25 plus shipping) for the PDP11/44 I recently acquired and now I can connect to the console >>> prompt after powering it on. Plus I figured out how to execute the firmware utility on the CMD CDU-720 (anyone have docs for this board?) so it appears that the system is fairly functional. However, after a while I noticed that some of the modules seemed to be running rather hot and then I noticed that one of the three fans is not working. I pulled out the fan tray and found that I can manually spin up the two good fans with little effort but the bad fan sticks and won't spin. These fans are labeled Torin TA450 Model A3102-10 35VAC 75Hz. Anyone know where a replacement fan could be obtained? _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963
